6To avoid damage to your door and/or
operator, make sure you disable any door
locks prior to installing your operator.
1Check your ceiling where the power
head of your new unit will be mounted.
Plan how you will be mounting the power head.
It is possible that ceiling joists may not be in the
exact position needed with respect to the garage
door operator. In any case, it may be necessary
to add an additional bracket and
fasteners (not
included with your new door operator kit).
2Check the wall directly above the garage
door.The door operator’s header bracket
must be securely fastened to this wall. Insure
that the structure will provide a strong mounting
location.
3Check to see if the mounting location
for the Safe-T-Beam®System “STB” is
clear from obstruction and has a wood
surface available for attaching the “STB”
brackets.The brackets may also be attached to
concrete if necessary but extra tools and special
fasteners (not supplied) will be required.
NOTE: 1-1/2" “STB” bracket adapters are
available through your local Overhead door Dealer.
4Is your garage door made of
light-weight steel, aluminum, fiberglass
or glass panels?Additional support bracing
must be added to these type doors. If this is the
case, please contact the door distributor or
manufacturer so that they can furnish you with a
“bracing kit.”
7Insure that your door is properly balanced
and moving freely. SEE WARNING BELOW.
8(NOT SHOWN) If your garage does not have
a separate entry door, you might want to
consider an emergency release kit (GER-2)for
installation on your garage door. See page Aat the
center of this manual.
5You need a 110-120 Volt power supply
available.If you plan to plug the unit into a
standard electrical outlet, is one available? The
outlet should be no more than about 3 feet from the
power head once it is mounted. (The cord is 4 ft. in
length.) SEE WARNING BELOW.

IMPORTANT
1. READ AND FOLLOW ALL SAFETY, INSTALLATION AND
OPERATION INSTRUCTIONS. If you have questions or
do not understand an instruction, call Overhead Door
Corp. or an authorized Overhead Door Dealer.
2. Do Not install operator on an improperly balanced door.
An improperly balanced door could cause severe injury.
Repairs and adjustments to cables, spring assembly, and
other hardware must be made by a trained service
person using proper tools and instructions.
3. Remove all ropes and disable all locks connected to the
door before installing operator.
4. Install door operator 7 feet or more above floor. Mount
emergency release knob 6 feet above floor.
To reduce the risk of severe injury or death:
WARNING :
5. Do Not connect the operator to the source of power
until instructed to do so.
6. Locate the control button:
•Within sight of door.
•At minimum height of 5 feet, so small children cannot
reach it.
•Away from all moving parts of the door.
7. Install the Entrapment WARNING Label next to the wall
button or wall console. Install the emergency release
tag on, or next to, the emergency release.
8. The operator must reverse when the door contacts a
1-1/2 inch high object on the floor at the center of the
doorway. This is the size of a 2” x 4” board laid flat.
HEADER AND DOOR
MOUNTING BRACKETS:
1. Finding header bracket mounting location.
•Close garage door.
–Use a pencil.
-Mark center of garage door (one-half overall
width) with 6” vertical line at top edge of door.
-Continue this line on wall above door for
about 12" (Fig. 2-1).
•Raise garage door until top edge of door
reaches its maximum height
(Fig. 2-2).
•Place door at highest point.
– Measure height from top edge of door to floor.
•Close door again.
•Mark height measurement on wall above door.
–Make your mark across vertical line
made earlier.
•Marking final height:
The 2 basic types of garage door mechanisms are:
Track guided doors–have rollers on each side
which ride in “tracks” to guide the door up and down.
Trackless doors–swivel on large spring loaded
hinges as the door opens and closes.
For track guided –add 2-1/2" to height mark just
made on
wall. This is location for header bracket.
NOTE: If spring or its shaft is in way, measure 2-1/2"
above spring or shaft and mark this height as your
location for header bracket.
For trackless –
add 6"- 12” to your height mark
just made on the wall. This is location for
header bracket.

2. Mounting the header bracket.
NOTE: Although header bracket may be oriented
several ways, method 1 is preferred if possible
because of added strength over other methods
(Fig. 2-5).
•Hold header bracket against wall
(Fig. 2-5).
–Place left edge on vertical line.
–Bottom edge on final height line.
• Mark screw hole locations on wall.
•Drill 5/32" pilot holes at each screw hole mark.

3. Finding door bracket mounting location.
•Door bracket is mounted as high on door as
possible along vertical centerline.
NOTE: In the case of sectional type doors, door
bracket must be mounted NO LOWER THAN top set
of rollers (Fig. 2-7).
For 1-piece doors, door bracket must be mounted at
top edge of door.
4. Mounting the door bracket.
•Proper bracing should be verified at this point.
–Align door bracket centered on your
vertical centerline.
–Attach using 3 self-drilling screws (42).
–Use lag screws (22) for solid wooden doors.
NOTE: For solid wood doors, carriage bolts
WITHOUT SLOTTED HEADS (not included, but
available by calling the Overhead Door help line) may
be used for attaching door bracket.
